Do Mobile Phones Cause Cancer? The Latest Research

For years, concerns have swirled around the potential link between mobile phone usage and cancer, primarily due to the radiofrequency electromagnetic fields emitted by these devices. Though, a extensive new review offers reassurance: the best available evidence suggests that mobile phones do not cause cancer.

The Science Speaks: No Link Found

A systematic review published in September 2024,commissioned by the World Health Institution (WHO),analyzed over 60 studies conducted between 1994 and 2022. This extensive analysis found no connection between mobile phones or wireless devices and cancer. This conclusion comes from a considerably larger dataset than previous investigations, offering a more robust assessment of the potential risks.

Early concerns and Conflicting Reports

Past investigations have yielded conflicting results,contributing to public apprehension. in 2011, the International Agency for Research into Cancer (IARC), a part of the WHO, classified mobile phone radiation as a “possible” human carcinogen. While this classification indicated some evidence linking mobile phones to cancer, the evidence was considered too weak to draw firm conclusions. This classification, even though tentative, fueled public concern and misinformation.

The initial concern stemmed from the fact that phones emit low-level radiofrequency electromagnetic fields when sending and receiving signals, and that phones are held close to the head during use. These associations caused people to be concerned that even a minimal absorption of radiation by the brain could have potential effects on health.

A More Rigorous Review

The 2024 systematic review employed stricter inclusion criteria compared to the 2011 IARC assessment. Researchers rigorously evaluated potential biases and considered varying elements of exposure risk. This meticulous approach strengthens the reliability of the findings.

Expert Opinion: Reassurance from the National Cancer Registry

Prof Deirdre Murray, director of the National Cancer Registry, welcomed the 2024 report. according to Murray, it “provides the best evidence to date that using mobile phones does not cause brain cancer. It also provides further reassurance that time spent on the phone or number of years using a mobile phone does not increase cancer. The findings of this report are consistent with what we have experienced in Ireland. Irish use of mobile phones has soared since 1994, but NCRI data shows that brain cancer incidence rates have remained stable.”

Long-Term Use and Cancer Rates

The research analysis revealed no association between long-term phone use (10 years or more) and brain cancer incidence. Furthermore, no link was found between the amount of phone use and brain cancer. Given the widespread and frequent use of mobile phones, researchers concluded that a critically important connection between mobile phones and cancer woudl likely have resulted in increased cancer diagnosis rates in the brain and neck. Simulation studies supported this conclusion, modeling potential cancer rates based on hypothetical causal effects.

IARC re-evaluation Likely

Due to the substantive findings of the 2024 review and other studies that have challenged the risks, IARC is likely to re-evaluate the classification of mobile phones as a “possible carcinogen”.

Other Risks to Consider

While the evidence suggests that mobile phones do not cause cancer, it is important to acknowledge other associated risks. These include distractions while driving and potential neurological effects on memory, learning, and cognitive function.

Conclusion: Comfort in the Science

While concerns about mobile phone safety have been prevalent, current scientific evidence offers reassurance. The 2024 WHO-commissioned review provides compelling evidence that mobile phones do not cause cancer. Stay informed about future research, but for now, find comfort in what the science says: “Mobile phones do not cause cancer.”
